Gareth Halfacree was having trouble with his newborn falling to sleep, and after learning that "white noise" and possibly various night light colours can help - designed the "Sleepduino".

If you're looking to recreate the Sleepduino for yourself, consider using our range of modules such as the super-bright RGB LED module:
and our SOUND piezo module:
